されている。[Prior art] Many hydrous compounds such as calcium chloride hexahydrate and sodium sulfate decahydrate have a high latent heat of fusion,
In addition, because many of them have a freezing point near normal temperature, they are beginning to be widely put into practical use in greenhouses for greenhouse horticulture and cultivation, residential heating, chemical heat pumps, solar heat storage tanks, industrial waste heat utilization equipment, etc. . Research has also been carried out on adding supercooling inhibitors or freezing point regulators to such hydrous compounds to stabilize the latent heat utilization temperature, or to adjust the utilization temperature itself. Prescription examples are being proposed one after another. On the other hand, much research has been conducted on heat storage capsules for effectively utilizing the latent heat of fusion possessed by these heat storage material compositions. For example, Japanese Utility Model Application No. 60-16883 discloses a capsule in which a spherical or elliptical capsule is provided with a sinkhole extending toward the center on its surface, and radial grooves are formed around the periphery of the sinkhole. Further, US Pat. No. 4,205,656 discloses a donut-shaped capsule provided with a cylindrical wall extending diametrically through the capsule.

得られている。 In addition, a plate-shaped capsule (Utility Application No. 59-170735), which was previously developed by the present applicant, is also attracting attention as an effective capsule. These heat storage capsules all focus on expanding the surface area that becomes an effective heat transfer surface, or suppressing the separation of solidification cores when melting and solidification are repeated, and have achieved some improvement effects. .

という難点がある。[Problems to be solved by the invention] By the way, the heat storage capsule is filled with heat storage material through the filling port and used in a completely sealed state. That is, as mentioned above, the heat storage capsule utilizes the property that the heat storage material absorbs heat when it solidifies and generates heat when it melts, and the heat storage material in use undergoes a phase change between solid and liquid phases. Coupled with changes in internal temperature, the inside of the capsule undergoes repeated pressurization and depressurization. Therefore, the filling port requires particularly excellent liquid tightness and sealing characteristics that can withstand changes in internal pressure, but the currently adopted sealing structure is not necessarily satisfactory when considering sealing workability and sealing effectiveness comprehensively. I can't say it's a thing. For example, the currently widely used sealing means is to provide a female thread at the filling port and a male thread throughout the entire body and screw them together. The threaded part may gradually loosen, causing liquid leakage. Another relatively simple method of sealing is to drive in a plug-like plug and make it fit, but with this method, the plug can fall out when subjected to pressure changes or external shocks as described above. The problem is that it is easy.

Furthermore, the present invention aims to provide a heat storage capsule having a sealing structure that can maintain an excellent sealing effect over a long period of time.

In the thermal storage capsule, the stopper has a rod having a length substantially the same as the thickness in the depth direction of the filling port, integrally protruding from the center of the disk, and a rod group of the disk. The gist is that an annular protrusion surrounding the rod is formed on the protruding side surface, and the stopper is fused and integrated at the inner peripheral surface of the filling port and the contact interface on the upper outer surface side. be.

る。 Heat is stored and radiated using the inner and outer walls of the doughnut-shaped hollow spherical container 1 as heat transfer walls. The diameter of the container is, for example, about 5 to 20 cmφ, and by filling a large number of capsules into a heat storage device and flowing a heat exchange medium into the device, heat is stored and released through the heat transfer wall. . In this case, if adjacent capsules 1 come in close contact with the opening of the through hole 2 and block it, the flow of the heat exchange medium (fluid) to the through hole 2 may be inhibited, leading to a decrease in heat storage/radiation efficiency. . Therefore, it is necessary to avoid this, for example, by providing a plurality of protrusions 4 on the periphery of both opening members of the through hole 2 as shown in FIG. As shown in the figure, a plurality of grooves 5 are provided on the periphery of both openings of the through hole, so that even if adjacent capsules 1 come into contact with both openings of the through hole, a gap for the heat exchange medium to pass through is guaranteed. It is better to leave it there. The shapes, sizes, etc. of the protrusions 4 and grooves 5 can be arbitrarily changed within a range that satisfies the purpose of ensuring a fluid passage gap.

れる。 The type of heat storage material composition filled in the capsule should be arbitrarily selected depending on the desired latent heat utilization temperature, and is not a limiting requirement of the present invention, but it is possible to store heat at a temperature around room temperature.・The most preferable material to be applied when dissipating heat is one based on calcium chloride hexahydrate, which may contain a crystal nucleating agent to prevent supercooling and a separation prevention agent as necessary. thickeners and stabilizers for

As shown in the figure (longitudinal cross-sectional view), if a large number of protrusions 6 are provided on the inner wall of the heat storage material composition storage chamber of the hollow spherical container 1, the protrusions 6 will function as shelves and generate crystal nuclei. Local concentrated deposition of the agent is prevented, and the supercooling suppressing effect is effectively exerted over a long period of time.

Therefore, there are no restrictions on the shape, structure, or molding method of the capsule body, and the present invention can of course be applied to flat capsules as shown in Utility Application No. 170735/1987, which was developed by the present applicant. .

の外径よりもやや小さめにしておくのがよい。 Next, the sealing structure of the heat storage material composition filling port 3, which is the most characteristic structure of the present invention, will be explained. This filling port 3 is sealed after filling the inside of the capsule with the heat storage material composition as described above, but during use, the internal pressure fluctuates due to the phase change or temperature change of the heat storage material composition as described above. However, this internal pressure change directly affects the sealing part of the filling port. Therefore, the filling port must be completely and firmly sealed to prevent liquid leakage. In order to meet these demands, the present invention uses a plug 7 having a structure as shown, for example, in FIGS. 6A and 6B, and seals the filling port 3 by fitting and fusion-bonding the plug 7 into the filling port 3. That is, this stopper 7 has a rod 7a integrally protruding from the center of a disc 7b, the length of which is approximately equal to the thickness (L 3 ) in the depth direction of the filling port 3, and the rod 7a of the disc 7b. Rod body 7a
An annular projection 7 is provided on the outer periphery of the protruding side so as to surround the rod.
c is integrally formed. The length L 7C of the annular projection 7c should be approximately equal to the upward protrusion length L 3C of the filling port 3, and the inner diameter of the annular projection 7c should be slightly smaller than the outer diameter of the protrusion of the filling port 3. .

ない。 In the present invention, the stopper 7 is fitted and fused to the filling port 3 to seal it. The specific means of fitting and fusing is not particularly limited, and for example, the filling port 3 and/or
Alternatively, it is also possible to adopt a method such as heating and melting the fitting surface of the plug 7 and driving it in, but as shown in FIG. 6A, the rod 7a of the plug 7 is made slightly thicker than the diameter of the filling port 7. At the same time, the inner surface of the annular projection 7c is opened downward, and its top side (lower surface of the disc 7b)
The plug 7 is formed to have a slightly narrower width than the outer diameter of the upwardly protruding portion of the filling port 3, and the plug 7 is pushed in while rotating at high speed, and the frictional heat generated at this time melts the fitting surface and creates a tight seal. If the fitting method is adopted, sealing can be performed quickly and reliably with a simple operation.Moreover, with such a sealing structure, the rod 7a
Since the entire fitting and fusion surfaces of the outer surface of the disc 7b, the lower surface of the disk 7b, and the inner surface of the annular protrusion 7c act as sealing surfaces, the heat storage material composition inside undergoes thermal expansion and cannot be removed from the plug 7. Even if internal pressure is applied in the exit direction, there is no fear that the stopper 7 will be pulled out and the heat storage material composition inside will leak. Moreover, since the plug 7 has both materials completely fused together at the joint interface between the inner surface and the upper outer surface of the filling port 3, there is no fear that the joint interface will become brittle or loosen over time. .

証される。 In addition, in the present invention, by making the length of the rod 7 a approximately equal to the thickness L 3 in the depth direction of the filling port 3,
In addition to maximizing the fusion area, the inner surface of the fusion part becomes almost flush in the fusion bonded state, so there is no notch (depression) formed on the inner surface and a stress concentration area. Excellent sealing effect is guaranteed.

り詰栓７が浮き上がるといつた問題を起こす。 Furthermore, in the present invention, as mentioned above, the annular projection 7 is provided on the stopper.
By providing c, the following effects can also be obtained in the fitting and fusing process. That is, when a stopper without an annular protrusion 7c is used, as shown in FIG. The rotation of the capper 7 and the filling port 3 may cause the area of heat fusion to become smaller due to the expansion of the area.
The bonding interface becomes slippery due to melting, causing problems such as, for example, the stopper 7 being lifted up by the internal pressure by the time it cools and solidifies, as shown in FIG.

もなく、確実な嵌合融着が可能となる。 However, when the plug 7 provided with the annular protrusion 7c is used as in the present invention, the annular protrusion 7c is fused while hugging the upper protrusion 3a during the fitting and fusing process by rotation, so that the annular protrusion 7c is fused while hugging the upper protrusion 3a. Filling port 3
There is no fear that the upper protrusion 3a will be pushed apart, and since the three-sided connection includes the inner surface of the annular protrusion 7c, the plug 7 will not lift up as shown in Fig. 8, and a secure fit and fusion can be achieved. It becomes possible to wear it.

Therefore, the shape of the stopper, the fitting and fusing method, etc. can be changed arbitrarily as long as it is compatible with the above purpose. In addition, the material for the stopper and capsule body is most commonly made of thermoplastic resin in order to smoothly perform the above-mentioned fitting and fusion, but any other material that can be temporarily melted can be heated. It may be made of a curable resin, or even made of an alloy with a relatively low melting point.
